IMPROVEMENT IN PADDLES.

Specification forming part of Letters Patent No. 129,012, dated July 16, 1872.

l Specification describing certain Improvements in Paddles for Boats, invented by CAL- VIN C. EVERsoN, of Palmyra, in the county of Wayne and State of New York.

Figure l is a side view of my improved paddle. Fig. 2 is a detail sectional View of the saine taken through the line a?, Fig. l. Fig. 3 is an end view of one ofthe paddles or wings, illustrating its construction.

Similar letters of reference indica-te'corresponding parts.

My invention has for its object to furnish an improved paddle or oar for propelling boats, which shall be so constructed as to encounter great resistance from the water when moving in the direction to propel the boat and very little resistance when moving back for another stroke; and it consists in the construction and combination of the various parts of the paddle, as hereinafter more fully described.

A represents an oar, having the handle al,

aperture a2, and open end frame a3. B are two lever-paddles, fulcrumed in bearings of frame a3 at a point on each side unequally distant from the two ends. C G are stops against which the paddlesrest while being drawn back. In, ornearlyin,avertical plane passingthrough the fulcrum-pins are vertexes of two plane angles, from which the planes incline in reverse frame a3; but when the motion is reversed and the Water presses through the frame outside thereof, and on the opposite long side of the paddles, the said paddles are thrown up against the stops C C in a perpendicular position. This allows the water to pass'freely through them.

Having thus described all that is necessary to a full understanding of my invention, what I esteem to be new, and desire to protect by Letters Patent, is-

The hand-oar A having frame a3, provided with a pair of paddles, B B, and stops C C, constructed and arranged as and for the purpose described.
